Happy Birthday Bill Gates!

Today Microsoft founder turned Philanthropist and Public Health Activist Bill Gates, turned 61! Congratulatory messages came in from all around world and all walks of life containing best wishes for one of the most celebrated man on the planet, a man who through Microsoft and his philanthropy work has touched the lives of millions of people around the work. Here are a few surprising facts about Bill Gates:

As a young teenager at Lakeside Prep School, Gates wrote his first computer program on a General Electric computer — it was a version of tic-tac-toe, where you could play against the computer.

Once his school realized Gates’ love for coding, they let him write the school’s computer program for scheduling students in classes. He even slyly altered the code so he was placed in classes with a “disproportionate number of interesting girls.”

Like many other successful tech entrepreneurs, Gates was a college dropout. He left Harvard University in 1975 to fully devote himself to Microsoft.

Gates was once arrested in New Mexico, in 1977. He was driving without a license and ran into a red light.

He used to fly in commercial airlines until 1997. Now, he has his own plane — he calls that his “big splurge.”

Despite his immense wealth, Gates says his kids will only inherit $10 million each — just a fraction of his $81.1 billion net worth. “Leaving kids massive amounts of money is not a favor to them,” he says.

Gates doesn’t know any foreign languages. That, he says, is his biggest regret in life thus far.

Gates says if Microsoft hadn’t worked out, he probably would’ve been a researcher for artificial intelligence

But, despite his deep interest in AI, Gates says he is “in the camp that is concerned about super intelligence.” That camp also includes notable leaders in science in technology, including Stephen Hawking and Elon Musk.

His favorite band? Weezer. He also calls U2 a “favorite,” and says he’s still “waiting for Spinal tap to go back on tour.”
